Human nature and social change

Our concept of human nature is certainly limited; it’s partially socially conditioned, constrained by our own character defects and the limitations of the intellectual culture in which we exist. Yet at the same time it is of critical importance that we know what impossible goals we’re trying to achieve, if we hope to achieve some of the possible goals. And that means that we have to be bold enough to speculate and create social theories on the basis of partial knowledge, while remaining very open to the strong possibility, and in fact overwhelming probability, that at least in some respects we’re very far off the mark.
